Abstract

Bei einem Viskosimeter mit rotierendem oder oszillierendem Meßprinzip sind eine mittels eines Antriebes um ihre Längsachse drehbare, im wesentlichen vertikale Meßwelle (3), die einen Rotor (6) aufweist, und ein dem Rotor gegenüberliegender Stator (5) vorgesehen, wobei ein zwischen dem Rotor und dem Stator gebildeter Raum zur Aufnahme einer Meßprobe bestimmt ist. Um die Reibungsverluste trotz einer konstruktiv sehr einfachen Lagerung der Meßwelle gering zu erhalten, wird vorgeschlagen, daß die Meßwelle an ihrem unteren Ende auf einer Kugel (10) aufliegt. Dabei kann der Rotor am unteren Ende der Meßwelle angeordnet sein und die Kugel zwischen den einander zugewandten Oberflächen des Rotors und des Stators liegen.
